First, i want to say that your locks dont look too bad, but the crochet hooks do some permanent damage. I started mine a year and a half ago with the backcombing method and palm rolling ALOT. When I found this site, i found out why palm rolling was harmful & stopped altogether, now my locks are softer and i dont worry about the bumps and zigzags anymore( just think as them adding more personality!) If you just keep washing how you are now and leave them alone, they will lock in time, its a long process but its worth it.

They'll be fine. Just wash them as you are doing. You can leave the ACV in for a few minutes longer for a bit more conditioning, coconut oil is excellent for conditioning. Get good quality coconut oil, put it on with your hands, rubbing it all over, the day before you are going to wash. The more they loosen the better.

were you washing with standard shampoo the stiffness maybe buildup if so use a anti residue or clarifying shampoo...once they are extremely toxic so only use them yo remove buildup not as a everyday wash

everything else said so far is right they will recover but slowly crochet recovery takes a long time and it delays proper dreading

Yes, the first year I washed with normal "silicone shampoo" and then I washed with a natural hair soap. I tried clarifying shampoo once because I wanted to remove all the silicone.And since 1 month I've been using baking soda. Nothing helped for the old "steel dreads" But I never tried oil...So I will try this.

I think my dreads are lucky because they only have been crocheted once So I'm full of hope!
